Occupational therapy runs on the same home health clocks as every other discipline, with one difference that shapes the whole schedule: under Medicare, OT can't start a case on its own, but it can keep one going. That means OT usually arrives after the nurse or the PT, often with less of the 60-day period left, and sometimes stays after they've gone.
This guide is for the home health OT, alone or working with a COTA, who plans their own visits. It covers when you can open a case and when you can't, what happens when you're the last discipline on, how to plan COTA visits around your 30-day visit, and how to time visits around the tasks you're treating. For the general system, start with how to manage a home health caseload.
A note on who is writing. I'm an occupational therapist and the founder of Logicly, a home health scheduling app for clinicians. The rules below are Medicare's; your state's practice act can add to them.
The Short Answer
- OT can't open a Medicare case alone. It is a dependent service until nursing, PT or SLP has established eligibility.
- OT can do the start of care when it is ordered with PT or SLP that establishes eligibility.
- OT can keep a case open. Once OT has been covered, a continuing need for OT qualifies on its own.
- Your 30-day visit is per discipline. The PT's reassessment does not reset your clock.
- Time visits to the task. Bathing and dressing in the morning, meal prep near a meal.
When OT Can Open a Case, and When It Can't
Medicare's list of qualifying services treats OT differently from the others:
Occupational therapy services in the current and subsequent certification periods (subsequent adjacent episodes) that meet the requirements of § 409.44(c) initially qualify for home health coverage as a dependent service as defined in § 409.45(d) if the beneficiary's eligibility for home health services has been established by virtue of a prior need for intermittent skilled nursing care, speech-language pathology services, or physical therapy in the current or prior certification period. (42 CFR 409.42(c)(4))
So an order for OT alone does not make a Medicare patient eligible for home health. Someone else's need does. What that means for who opens the case:
| Services ordered | Who makes the initial assessment visit | Source |
|---|---|---|
| Nursing, with or without therapy | The registered nurse | 42 CFR 484.55(a)(1) |
| PT only, or PT and OT | The PT; or the OT, because OT is ordered with PT, which establishes eligibility | 42 CFR 484.55(a)(2) |
| SLP and OT | The SLP, or the OT on the same basis | 42 CFR 484.55(a)(2) |
| OT only (Medicare) | The OT cannot open it; OT is not a qualifying service on its own | 42 CFR 409.42(c)(4) |
The comprehensive assessment follows the same rule (42 CFR 484.55(b)(3)). When you do open, the clocks are the same as for anyone: the initial visit within 48 hours of the referral or on the ordered start of care date, and the comprehensive assessment within 5 calendar days.
Arriving Late: Scheduling the OT Evaluation
More often, OT is added after the case opens: the RN or PT sees a need and asks for an OT order. By then the certification period is already running, and every day before your evaluation is a day your frequency doesn't have.
- Ask when the case opened and when the period ends. If the patient is in week 3 of 9, a 2w6 order has to fit in the weeks that are left.
- Evaluate early in the week when you can, so the first treatment visit can follow the same week.
- Coordinate with the PT. Two therapy visits on the same day can wear out a patient who is only a week out of the hospital. Ask which days the PT or PTA is coming and take different ones.
When OT Is the Last Discipline On
Once OT has been covered, the rule turns in your favour:
Subsequent to an initial covered occupational therapy service, continuing occupational therapy services which meet the requirements of § 409.44(c) are considered to be qualifying services. (42 CFR 409.42(c)(4))
If the PT discharges at week 5 and the patient still needs skilled OT for bathing safety and home management, the patient can stay on service for OT alone. That changes your schedule in three ways:
- The recert becomes yours. If the patient is still on service at the end of the period, someone has to do the recertification in its last 5 days (42 CFR 484.55(d)(1)). With nursing and PT gone, plan on it being you.
- So does the discharge. When the goals are met, put the discharge visit on the calendar the week before, and tell the office.
- Watch for the 30-day clock if a COTA has been carrying the visits.
Planning COTA Visits Around Your 30-Day Visit
At least every 30 calendar days a qualified therapist (instead of an assistant) must provide the needed therapy service and functionally reassess the patient. (42 CFR 409.44(c)(2)(i)(B))
The clock starts with the first OT visit and resets each time you see the patient. It is per discipline: the PT's 30-day visit resets the PT's clock, not yours. Counting starts the day after your visit, so a reassessment on April 1 means you must be back by May 1, with no grace period.
- Book your next visit for around day 21 to 28 at the reassessment, so a cancellation doesn't push it past 30.
- Count it as one of the week's ordered OT visits; the COTA makes the rest.
- Keep your visit and the COTA's on different days in the same week.
A COTA visit is an occupational therapy visit under the OT order; there is no separate COTA order. Which order an assistant works under and the 30-day therapy reassessment rule cover both in full.
Time Visits to the Task
This is the part of OT scheduling the rules don't cover and the patient notices most. You can't assess a morning routine at 3 pm.
| What you're treating | When to schedule it | Why |
|---|---|---|
| Bathing, dressing, grooming | Morning, when the patient would really do it | You see the real routine, the real bathroom, the real fatigue |
| Meal preparation and kitchen safety | Before a meal | The task is real, and the patient eats what they made |
| Medication management | When the patient takes the morning or evening dose | You see the system they use, not a demonstration of it |
| Caregiver training | When the caregiver is home | The person doing the task has to be there |
| Home safety and equipment | Daylight, after the equipment is delivered | Measure and practice with the real thing |
Put these on the patient's record as times the patient can be seen best, and place them before the routine visits that can go anywhere. They are the OT equivalent of a nurse's insulin visit: the time is part of the treatment.
What to Want From a Scheduling App
For an OT, a home health scheduling app helps most with the parts above that are easy to lose: how much of the cert period is left when you start, where your 30-day visit falls, which patients you can only see at certain times, and when the case becomes yours to recert.
In Logicly, the cert periods and recert window are worked out from the start of care, so a late OT evaluation shows you how many weeks are left. You type the order as written on the Frequency tab, and the times a patient can't be seen go on their Availability tab. To keep a morning ADL visit fixed, Lock this time on the visit keeps it where it is when you optimize the day's route. The visits the week still needs wait in the visit pool for you to place, or for Auto-schedule week to spread across your working days in driving order. Logicly shows your own caseload, so plan your COTA's visits with them. You can try it on sample patients without signing up, and we compare the other options in the best home health apps for clinicians.

Logicly works out each patient's cert period and recert window from the start of care, keeps fixed-time visits where they are, and places the rest in driving order.
Key Takeaways
- OT can't open a Medicare case alone; it can do the start of care when ordered with PT or SLP that establishes eligibility.
- Once covered, continuing OT is a qualifying service. When OT is the last discipline on, the recert and the discharge are yours.
- Schedule a late OT evaluation early in the week, and check how much of the 60-day period is left.
- Your 30-day visit is per discipline. Book it for day 21 to 28 and count it as one of the week's OT visits.
- Time ADL visits to the task: the routine is part of the treatment.
Frequently asked questions
Can occupational therapy open a Medicare home health case?
Not on its own. Under 42 CFR 409.42(c)(4), occupational therapy can initially qualify for home health only as a dependent service, when eligibility was established by a need for skilled nursing, physical therapy or speech-language pathology in the current or prior certification period. An OT-only Medicare referral can't be opened by the OT. When OT is ordered with PT or SLP that establishes eligibility, the OT may do the initial and comprehensive assessments.
Can OT keep a home health case open after PT discharges?
Yes. Once occupational therapy has been covered, a continuing need for OT is a qualifying service (42 CFR 409.42(c)(4)). If PT or nursing discharges and the patient still needs skilled OT, the patient can stay on service for OT alone, and the OT then carries the recertification and, eventually, the discharge.
How often does an OT have to see a patient a COTA is treating?
At least every 30 calendar days. A qualified occupational therapist, instead of the assistant, must provide the therapy service and functionally reassess the patient (42 CFR 409.44(c)(2)(i)(B)). The clock is per discipline, so the PT's visit does not reset the OT's clock. State practice acts can add their own COTA supervision rules.
When should I schedule an OT evaluation in home health?
As soon after the start of care as the orders allow, because the OT frequency starts from your evaluation and the 60-day period is already running. Ask the office when the RN or PT opened the case and whether OT was on the referral or added later. Plan the evaluation for a time of day when you can see the tasks you are evaluating, such as morning for bathing and dressing.
